To better understand how the seal family is related to other pinniped families, it is important to understand their phylogenetic tree – or family tree. Seals belong to the order Carnivora, a group of mammals that must eat animals to survive.

They often eat herbivorous animals, but sometimes also omnivores or even other carnivorous animals. Seals, sea lions and walruses eat fish, crustaceans, squid, octopuses, birds and sometimes other seals! Other animals that belong to the order Carnivora are lions, wolves, and bears, to name a few.

Carnivores are then often divided into one of two suborders, the Feliformia and the Caniformia. The suborder Feliformia is comprised of the cats, hyenas, mongooses, and civets. The suborder Caniformia includes dogs, wolves, bears, weasels, raccoons, and pinnipeds, among others.
